Abstract Share this page

Researchers in some studies (1–3) have documented a marked increase in the use of mammography throughout the United States from the middle 1980s to the present. Although some results remain controversial, those in most clinical trials of mammography indicate reduced breast cancer mortality among screened women. In the United States, two major organizations recommend screening every 1–2 years for women 40 years and older (4,5). In the United Kingdom and most of Europe, screening is performed every 2–3 years. To our knowledge, in no U.S. study has an evaluation been conducted about whetherdifferences in the time since previous mammography affect performance parameters, and very few investigators include sensitivity in their comparison of measures of screening performance. Thus, the purpose of our study was to evaluate whether there is an association between the number of months since previous mammography (MSPM) and performance measures (sensitivity, specificity, recall rate, cancer detection rate, and positive predictive value [PPV]) in women who underwent U.S. community-based screening mammography.
